Description
Technical Field

Background
In recent years, the application and development of the neodymium iron boron permanent magnet material are very rapid, and the success or failure of the protection of the neodymium iron boron permanent magnet material is one of the key technologies which relate to the popularization and application of the material.
The application of the neodymium iron boron permanent magnet material is premised on solving the problem of corrosion resistance of the neodymium iron boron permanent magnet material; as a porous material prepared by a powder metallurgy process, intergranular corrosion is easily formed on the main phase and the boundary phase of neodymium-iron-boron because of a neodymium-rich phase, and the corrosion resistance of the whole neodymium-iron-boron alloy is very poor due to the active property of a rare earth element neodymium in the neodymium-iron-boron powder alloy, so that the neodymium-iron-boron alloy is very easy to rust and corrode in a damp and hot environment, the service life of a neodymium-iron-boron permanent magnet is seriously influenced due to the reduction or damage of the magnetic property caused by corrosion failure, and the stability and the reliability of the product are reduced.
At present, common neodymium iron boron permanent magnet material anticorrosion methods comprise surface coating + heat treatment, electrophoretic deposition + heat treatment, evaporation + heat treatment, magnetron sputtering + heat treatment and the like. The heat treatment is an important process for forming a deep blue protective layer on the surface of the neodymium iron boron magnet, and heavy rare earth elements on the surface are diffused into the magnet along a grain boundary by adjusting the temperature and time of the heat treatment to form a core-shell structure. However, the diffusion speed of the heavy rare earth elements from the surface of the magnet into the interior of the magnet along the grain boundary of the magnet is very slow, the diffusion time is long, and a large amount of energy is consumed. The neodymium iron boron magnet after heat treatment also needs to be cleaned, dried and other processes, the existing bluing heat treatment equipment and the existing cleaning and drying equipment are mostly arranged independently, materials need to be transferred frequently in the processes, the continuity is poor, the production efficiency is low, the equipment investment and the labor cost are increased, and the neodymium iron boron magnet is not suitable for mass production.
